if you use single disk in ZFS or ZFS mirror, only 2GB is enought (some users use only 1GB viewtopic.php?f=15&t=3993) and works, but I do not recommend to use ZFS in this low RAM system UFS is better fot this cases.

If you want to use raidZ1 and more of 3 disk ( IE:5 disk, 4 GB is minimun and 8 GB is recommended) notice that works if you have only 2GB but probably you need to disble prefetch in ZFSkerntune to have a "stable" system.
12.1.0.4 - Ingva (revision 7743) on SUPERMICRO X8SIL-F 8GB of ECC RAM, 11x3TB disk in 1 vdev = Vpool = 32TB Raw size , so 29TB usable size (I Have other NAS as Backup)
